[0060] When an existing air conditioner sterilizes a user's skin or clothes with an ultraviolet sterilization device, the radiation amount usually exceeds a threshold or is insufficient.

[0061] like Figure 1 As shown, the present invention provides a sterilization control method for an air conditioner 100, the air conditioner 100 includes an indoor unit 1 and a sterilization module 2, the indoor unit 1 is installed indoors, and the sterilization module 2 is installed in the indoor unit 1, for radiating light of a wavelength range that inactivates microorganisms and / or viruses to the room where the air conditioner 100 of the present invention is installed. Specifically, the sterilization module 2 is an ultraviolet sterilization lamp, so that when the air conditioner 100 is running in the sterilization mode, the air conditioner 100 controls the ultraviolet sterilization lamp to emit ultraviolet rays of a wavelength suitable for the human body, so as to achieve the destruction of the molecular structure of deoxyribonucleic acid or ribonucleic acid in the cells of the microorganism body, and at the same time, it can also reduce the damage of ultraviolet rays to human skin cells, so that it can achieve sterilization of the human body while ensuring the safety of the human body.

[0062] like Figure 1 As shown, the air conditioner 100 of the present invention further includes a humidity sensor and a camera. The humidity sensor is used to detect the indoor air humidity. The camera is used to obtain image information of indoor people, and use a neural network model to process the image information of indoor people to obtain user information of indoor people. More specifically, the air conditioner 100 can obtain the number of indoor people through the camera, and can also obtain the location information of indoor people.

[0063] In the present invention, the air conditioner 100 further includes a controller (not shown), which is connected to the humidity sensor and the camera respectively, so that the controller can control the operation of the sterilization module 2 according to the indoor air humidity and the parameter information of the personnel. It should be noted that the controller can be a control chip of the air conditioner 100 itself, or a control module specifically used to execute the control method of the present application, or a functional unit of the control module.

[0064] Below, refer to Figures 2 to 10 To illustrate the possible implementation of the sterilization control method of the air conditioner of the present invention.

[0065] like Figure 2 As shown, in a possible implementation manner, the sterilization control method of the air conditioner of the present invention comprises the following steps:

[0066] S101: Obtain indoor air humidity;

[0067] S102: Obtain parameter information of people in the room;

[0068] S103: determining the cumulative amount of light irradiated to the personnel during the sterilization period from the start time of turning on the sterilization mode to the current time within a preset time period according to the air humidity and parameter information;

[0069] S104: Controlling the operation of the sterilization module according to the comparison result between the cumulative irradiation amount and the preset irradiation amount threshold.

[0070] In S101, the indoor air humidity is obtained by the humidity sensor. Specifically, the humidity sensor is installed in the room to detect the indoor air humidity. More specifically, in other embodiments of the present invention, the humidity sensors can also be evenly distributed in the room so that the humidity sensor can detect the indoor air humidity more accurately to ensure the sterilization performance of the air conditioner.

[0071] In S102, the camera obtains parameter information of the people in the room. Specifically, the camera can obtain the number and position information of the people in the room. More specifically, the camera can be a stereoscopic vision camera, a laser radar camera, or a multi-eye camera, so that the camera can obtain the number of people in the room and the coordinate information of the people in the room relative to the camera. It should be noted that in other embodiments of the present invention, the camera can also obtain image information of the people in the room, and use a neural network model to process the image information of the people in the room to obtain user information of the people in the room, so that when the air conditioner sterilizes the room, it can directly identify whether the people in the room are permanent residents in the room or temporary passers-by. For example, the camera can directly identify whether the people in the room are employees or cleaning staff. If they are cleaning staff, since the cleaning staff only needs to stay in the room with the air conditioner equipped with the sterilization function for a short time, it is not necessary to adjust the operation of the sterilization module according to the position parameters of the cleaning staff. At this time, the air conditioner only needs to adjust the operation of the sterilization module according to the parameter information of the employees in the room.

[0072] In S103, the air conditioner determines the cumulative exposure of the indoor personnel to ultraviolet rays during the sterilization period from the start time of the sterilization mode to the current time within a preset time period according to the obtained air humidity and personnel parameter information. Specifically, the inventors found in the process of realizing the present invention that even if the ultraviolet sterilization lamp emits ultraviolet rays with a wavelength of 222nm, which is relatively safe for the human body, the human body still has an exposure threshold that can be tolerated. After the exposure of the human skin to 222nm ultraviolet rays exceeds the exposure threshold, the ultraviolet rays will cause harm to the human body. Therefore, in the process of the air conditioner of the present invention sterilizing the indoor personnel through the sterilization module, the operation of the sterilization module is controlled according to the parameter information of the indoor personnel, so that the cumulative exposure of the indoor personnel to ultraviolet rays is lower than the exposure threshold. More specifically, the exposure threshold is the maximum exposure dose received by the human cornea in one day: 160mJ / cm2 , where the time period is: one day.

[0073] In S104, the air conditioner controls the operation of the sterilization module according to the comparison result between the cumulative exposure amount of ultraviolet rays to the indoor personnel and the exposure amount threshold so that the cumulative exposure amount to the indoor personnel is less than the exposure amount threshold, thereby ensuring the safety of the indoor personnel while ensuring the sterilization effect of the air conditioner.

[0074] like Figure 3 As shown, in a possible implementation manner, the sterilization control method of the air conditioner of the present invention further includes the following steps:

[0075] S201: Recording multiple distance information of multiple persons during the sterilization period according to multiple location information;

[0076] S202: Determine multiple accumulated exposure amounts corresponding to multiple people during the sterilization period according to air humidity, multiple distance information and multiple sterilization time information.

[0077] In S201, when the present invention is implemented, the number of people in the room is at least two, so the air conditioner determines the distance information between the multiple people in the room and the sterilization module based on the position information of the multiple people in the room obtained by the camera.

[0078] It should be noted that, although the number of people in the room described above is at least two, this is not restrictive. When the present invention is implemented, the number of people in the room may also be one. In addition, the inventors also found in the process of implementing the present invention that when the ultraviolet sterilization lamp radiates ultraviolet light into the room, the intensity of ultraviolet light irradiation received by the people in the room is proportional to the distance from the sterilization module, which results in the faster increase in the cumulative amount of ultraviolet light irradiation received by the people who are closer to the sterilization module.

[0079] In S202, the inventors also found in the process of implementing the present invention that in the process of the air conditioner radiating ultraviolet light into the room through the ultraviolet sterilization lamp, the intensity of ultraviolet radiation received by the indoor personnel is also related to the indoor air humidity. Specifically, when the sterilization power of the sterilization module and the distance between the personnel and the sterilization module remain unchanged, the higher the indoor air humidity, the lower the radiation intensity received by the personnel. Therefore, when the present invention is specifically implemented, the air conditioner can determine the cumulative radiation received by multiple personnel according to the indoor air humidity, the distance information of multiple people from the sterilization module and multiple sterilization time information. It should be noted that when the present invention is specifically implemented, the controller of the air conditioner obtains the position information of multiple people in the room, and the controller records the sterilization time information received by multiple people in the room. In this way, when multiple people in the room move, the controller can also determine the change of the radiation intensity received by multiple people according to the change of the position of multiple people, so that the cumulative radiation received by multiple people can be determined more accurately.

[0080] like Figure 4 As shown, in a possible implementation manner, the sterilization control method of the air conditioner of the present invention further includes the following steps:

[0081] S301: calling a preset first mapping relationship table storing air humidity, distance information and illumination intensity;

[0082] S302: Determine multiple radiation intensities received by multiple persons according to air humidity, multiple distance information and a first mapping relationship table;

[0083] S303: Determine a plurality of accumulated exposure amounts corresponding to a plurality of personnel during the sterilization period according to the sum of the products of a plurality of exposure intensities and a plurality of sterilization time information.

[0084] In S301, a first mapping relationship table of air humidity, distance information and irradiation intensity is stored inside the controller, and the first mapping relationship table may be determined in advance by a designer based on experiments. It should be noted that, although the first mapping relationship table described above is preset to be stored inside the controller, this is not restrictive, and in other embodiments of the present invention, the first mapping relationship table may also be stored in a local database, a cloud database or a network database.

[0085] In S302, after receiving the air humidity and multiple distance information, the controller can compare them with the first mapping relationship table to determine the radiation intensity to which multiple persons are subjected. It should be noted that since the multiple distance information corresponds to the sterilization time information, the radiation intensity determined by the air conditioner of the present invention based on the multiple distance information and the air humidity information also corresponds to the sterilization time information of multiple persons in the room.

[0086] In S303, the air conditioner determines a plurality of cumulative exposure amounts corresponding to a plurality of persons during the sterilization period of the air conditioner according to the sum of the products of the determined plurality of exposure intensities and the plurality of sterilization time information. In the specific implementation of the present invention, since the exposure intensity corresponds to the sterilization time information of a plurality of persons in the room, the air conditioner can obtain different cumulative exposure amount values ​​for each person, so that the air conditioner can determine the cumulative exposure amount received by each person, thereby ensuring the safety performance and sterilization effect of the air conditioner.

[0087] like Figure 5 As shown, in a possible implementation manner, the sterilization control method of the air conditioner of the present invention further includes the following steps:

[0088] S401: Obtaining the sterilization power of the sterilization module;

[0089] S402: Determine multiple accumulated exposure amounts corresponding to multiple personnel during the sterilization period according to air humidity, multiple distance information, multiple sterilization time information and sterilization power.

[0090] In S401, the controller obtains the sterilization power of the sterilization module during the sterilization period.

[0091] In S402, the inventors also found in the process of implementing the present invention that the irradiation intensity of the ultraviolet germicidal lamp on the indoor personnel is also related to the sterilization power of the ultraviolet germicidal lamp, so the air conditioner can also determine the cumulative irradiation amount received by multiple personnel according to the air humidity, the distance information of multiple personnel from the sterilization module, multiple sterilization times and the sterilization power of the sterilization module. It should be noted that when the present invention is implemented, the controller of the air conditioner obtains the position information of multiple personnel in the room, and the controller records the sterilization time information received by multiple personnel in the room. In this way, when multiple personnel in the room move, the controller can also determine the change of the irradiation intensity received by multiple personnel according to the change of the position of multiple personnel, so that the cumulative irradiation amount received by multiple personnel can be determined more accurately.

[0092] like Figure 6 As shown, in a possible implementation manner, the sterilization control method of the air conditioner of the present invention further includes the following steps:

[0093] S501: calling a preset second mapping relationship table storing air humidity, distance information, sterilization power and irradiation intensity;

[0094] S502: Determine multiple irradiation intensities to which multiple persons are subjected according to air humidity, multiple distance information, sterilization power, and a second mapping relationship table;

[0095] S503: Determine a plurality of accumulated exposure amounts corresponding to a plurality of personnel during the sterilization period according to the sum of the products of a plurality of exposure intensities and a plurality of sterilization time information.

[0096] In S501, a second mapping relationship table of air humidity, distance information, sterilization power and irradiation intensity is stored inside the controller, and the second mapping relationship table may be determined in advance by the designer based on experiments. It should be noted that although the second mapping relationship table described above is preset and stored inside the controller, this is not restrictive. In other embodiments of the present invention, the second mapping relationship table may also be stored in a local database, a cloud database or a network database.

[0097] In S502, after the controller receives the air humidity, multiple distance information and sterilization power, it can compare with the second mapping relationship table to determine the irradiation intensity received by multiple people. It should be noted that in the specific implementation of the present invention, when the sterilization power of the sterilization module is adjustable, the controller records the corresponding relationship between multiple sterilization time information and sterilization power, and since multiple distance information also corresponds to the sterilization time information, then the irradiation intensity determined by the air conditioner of the present invention according to the air humidity, multiple distance information, and sterilization power information also corresponds to the sterilization time information of multiple people in the room. Through the above setting method, even if the sterilization power of the sterilization module of the air conditioner of the present invention changes, the air conditioner can still determine the cumulative exposure amount of ultraviolet light received by multiple people in the room, thereby further ensuring the sterilization performance of the air conditioner.

[0098] In S503, the air conditioner determines a plurality of cumulative exposure amounts corresponding to a plurality of personnel during the sterilization period according to the sum of the products of the determined plurality of exposure intensities and the plurality of sterilization time information. In the specific implementation of the present invention, since the exposure intensity corresponds to the sterilization time information of a plurality of personnel in the room, the air conditioner can obtain different cumulative exposure amount values ​​for each person, so that the air conditioner can determine the cumulative exposure amount received by each person, thereby ensuring the safety performance and sterilization effect of the air conditioner.

[0099] like Figure 7 As shown, in a possible implementation manner, the sterilization control method of the air conditioner of the present invention further includes the following steps:

[0100] S601: Obtaining a first maximum cumulative value among a plurality of cumulative exposure amounts;

[0101] S602: When the first maximum cumulative value is greater than or equal to the irradiation threshold, stop the sterilization mode.

[0102] In a specific implementation of the present invention, a controller obtains a first maximum cumulative value among multiple cumulative exposure amounts, and when the first maximum cumulative value is greater than or equal to an exposure threshold, the sterilization module is controlled to stop releasing ultraviolet rays, so that as long as the cumulative exposure amount of one of the multiple people in the room is greater than or equal to the exposure threshold, the sterilization mode of the air conditioner is stopped, so as to avoid physical damage to the people in the room due to the cumulative exposure amount of ultraviolet rays exceeding the exposure threshold.

[0103] like Figure 8 As shown, in a possible implementation manner, the sterilization control method of the air conditioner of the present invention further includes the following steps:

[0104] S701: After detecting that the person corresponding to the first maximum cumulative value has left the room, controlling the sterilization module to turn on the sterilization mode again and continue to determine the cumulative exposure amount;

[0105] S702: Obtaining a second maximum cumulative value among a plurality of cumulative exposure amounts;

[0106] S703: When the second maximum cumulative value is greater than or equal to the irradiation threshold, the sterilization mode is stopped again until multiple people leave the room.

[0107] In S701, after the air conditioner detects that the first maximum cumulative value of the accumulated exposure to ultraviolet rays to people in the room is greater than the exposure threshold, if the camera detects that the person corresponding to the first maximum cumulative value has left the room, and the cumulative exposure to ultraviolet rays to the remaining people in the room is less than the exposure threshold, the controller controls the sterilization module to turn on the sterilization mode again to release ultraviolet rays into the room to continue sterilizing the remaining people in the room, so as to further ensure the sterilization effect of the air conditioner.

[0108] It should be noted that, in the specific implementation of the present invention, the controller can obtain the user information of the indoor personnel based on the image information obtained by the camera, and the controller can record the corresponding relationship between the user information of the personnel and the cumulative exposure amount of ultraviolet rays received by the personnel, so that the controller can more accurately determine the cumulative exposure amount of ultraviolet rays received by each person. In addition, in the specific implementation of the present invention, if the camera detects that a person whose cumulative exposure amount of ultraviolet rays is greater than the exposure threshold returns to the room after leaving the room for a period of time, the controller can also control the sterilization module to stop releasing ultraviolet rays into the room to ensure the safety of the people in the room.

[0109] In S702, after the camera detects that a person whose cumulative exposure to ultraviolet rays is greater than the exposure threshold has left the room, and the controller controls the sterilization module to turn on the sterilization mode again, the controller obtains the second maximum cumulative value of the multiple cumulative exposures corresponding to the multiple people in the room, so that the air conditioner can continue to detect the cumulative exposure to ultraviolet rays received by the remaining people in the room, so that the air conditioner can always detect the maximum value of the cumulative exposure received by multiple people in the room, which can further ensure the safety performance of the air conditioner.

[0110] like Fig. 9 As shown, in a possible implementation manner, the sterilization control method of the air conditioner of the present invention further includes the following steps:

[0111] S801: Acquire multiple historical parameter information corresponding to multiple persons in the room, where the multiple historical parameter information includes multiple historical position information corresponding to the multiple persons and multiple historical sterilization time information corresponding to the multiple historical position information;

[0112] S802: Determine multiple daily distance information of multiple personnel from the sterilization module within a time period according to multiple historical location information and multiple historical sterilization time information;

[0113] S803: Acquire the minimum daily distance information among the multiple daily distance information;

[0114] S804: Determine the average length of time that multiple people stay in the room within a time period according to multiple pieces of historical sterilization time information;

[0115] S805: Determine the sterilization power based on the minimum daily distance information, average duration, air humidity and exposure threshold.

[0116] In S801, when the present invention is implemented, the controller can record historical parameter information corresponding to multiple people in the room. Specifically, the multiple historical parameter information includes historical location information corresponding to the multiple people and multiple historical sterilization time information corresponding to the multiple historical location information.

[0117] In S802, the controller determines the daily motion trajectory information of multiple people in the room within a time period according to the multiple historical position information and the multiple historical sterilization time information, and then determines the daily distance information of multiple people from the sterilization module within a time period according to the determined multiple daily motion trajectory information. It should be noted that the daily distance information is the distance information between the specific position where the indoor personnel stay for a long time and the sterilization module. Specifically, the specific position can be the workstation of the indoor personnel, or the bed in the bedroom. Obviously, the specific position can also be other types of positions that allow the indoor personnel to stay for a long time. In the above manner, the air conditioner of the present invention can determine the motion patterns of multiple people in the room according to the historical parameter information of multiple people in the room. For example, when the room is an office place for multiple people, the multiple people will stay at their own workstations most of the time. At this time, a large proportion of the time in the sterilization time information will correspond to the position information of the workstations of the indoor personnel, thereby determining multiple daily distance information corresponding to the multiple people.

[0118] In S803, the controller obtains the minimum daily distance information among the multiple daily distance information, that is, obtains the shortest distance between multiple workstations or beds of multiple personnel in the room and the sterilization module.

[0119] In S804, the controller determines the average length of time that multiple people stay in the room in one day according to multiple historical sterilization time information.

[0120] In S805, the controller determines the sterilization power of the sterilization module based on the minimum daily distance information, average duration, air humidity and exposure threshold, so that the air conditioner can determine the sterilization power of the sterilization module based on the indoor air humidity, average duration and minimum daily distance information of the day, so that the cumulative exposure of the person closest to the sterilization module in one day is as equal to the exposure threshold as possible, thereby ensuring the safety performance of the air conditioner, and also enabling the sterilization module to always radiate ultraviolet rays into the room during this average duration, so that the air conditioner can maintain the longest possible sterilization work for multiple people entering the room, so as to reduce the risk of bacteria or viruses spreading between multiple people, thereby ensuring the sterilization effect of the air conditioner.

[0121] like Fig.10 As shown, in a possible implementation manner, the sterilization control method of the air conditioner of the present invention further includes the following steps:

[0122] S901: calling a third mapping relationship table preset to store minimum daily distance information, average duration, air humidity, irradiation threshold and sterilization power;

[0123] S902: Determine the sterilization power according to the minimum daily distance information, the average duration, the air humidity, the irradiation threshold and the third mapping relationship.

[0124] In S901, a third mapping relationship table of minimum daily distance information, average duration, air humidity, irradiation threshold and sterilization power is stored inside the controller, and the third mapping relationship table can be determined in advance by the designer based on experiments. It should be noted that although the third mapping relationship table described above is preset and stored inside the controller, this is not restrictive. In other embodiments of the present invention, the third mapping relationship table can also be stored in a local database, a cloud database or a network database.

[0125] In S902, after the controller receives the minimum daily distance information, average duration, air humidity and irradiation threshold, it can compare with the third mapping relationship table to determine the sterilization power of the sterilization module.

[0126] As a possible implementation, this embodiment further provides an air conditioner, which includes the above-mentioned sterilization module.

[0127] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0128] It should be noted that although the detailed steps of the method of the present application are described in detail above, without departing from the basic principles of the present application, technical personnel in this field can combine, split and change the order of the above steps. The modified technical solution does not change the basic concept of the present application and therefore falls within the scope of protection of the present application.

[0129] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
